Optional Network Resource Requirements
If the resources discussed in this section are used, the applicable servers must be available at all times and in close physical proximity to Cisco Unity Connection (over a local area network, not a wide area network), or Connection functionality will be impaired. See the following sections:
Use of Dynamic Host Configuration Protocol (DHCP) is optional with Cisco Unity Connection and can be used to automatically configure network settings on the Connection server. If DHCP is not used, network settings such as hostname, IP address, IP mask, and gateway address must be manually entered during install or configured after install by using the command line interface.
Use of DNS name resolution is optional with Cisco Unity Connection, but if available, is recommended for use with Connection. If DNS name resolution is not enabled, IP addresses (not hostnames) should be used for all network devices.
When you are using Exchange 2007 or Exchange 2003 as a calendar application, you can configure Cisco Unity Connection to allow users to do several meeting-specific tasks by using the phone, for example, to hear a list of the participants for a meeting, send a message to the meeting organizer, or send a message to the meeting participants. Meeting organizers can also cancel a meeting. In addition, if users are using Microsoft Outlook, they can hear a list of upcoming meetings, and accept or decline meeting invitations.
Connection also enables users to import Exchange contacts by using the Cisco Unity Assistant web tool. The contact information can then be used in rules that users create in the Cisco Unity Personal Call Transfer Rules web tool and when users place outgoing calls by using voice commands.
Connection can play Exchange email over the phone by using Text to Speech.
See the System Requirements for Cisco Unity Connection Release 7.x for more information on supported versions of Microsoft Exchange for accessing calendar information, importing personal contacts, and accessing email. Also see the "Creating Calendar Integrations" and the "Configuring Access to Emails in an External Message Store" chapters of the System Administration Guide for Cisco Unity Connection Release 7.x.
Cisco Unity Connection can optionally use an LDAP directory (for example, Microsoft Active Directory) for LDAP directory synchronization and authentication. See the System Requirements for Cisco Unity Connection Release 7.x for more information on supported LDAP directories. See the "LDAP Directory Integration with Cisco Unity Connection" chapter for design considerations when integrating Connection with an LDAP directory.
